If a PACKET ACCESS REJECT message is received from the new cell, the mobile station shall start timer T3176, return to the old cell and send a PACKET CELL CHANGE FAILURE message to the network.
If the mobile station was in uplink packet transfer before the cell change, the mobile station shall establish a new uplink TBF and send the PACKET CELL CHANGE FAILURE message on this TBF. The mobile station shall then resume its uplink transfer on this TBF.

In the following cases, the mobile station shall determine that the network controlled cell reselection procedure has failed:
• Access is denied in the new cell (i.e., the mobile station receives an IMMEDIATE ASSIGNMENT REJECT, a PACKET ASSIGNMENT REJECT or, in a UTRAN cell, an RRC CONNECTION REJECT message). Cause: “Immediate Assign Reject or Packet Access Reject on target cell”.
The mobile station shall send a PACKET CELL CHANGE FAILURE message with the appropriate cause value to the network in the old cell and stop timer T3176. The PACKET CELL CHANGE FAILURE message may be sent on PACCH when the mobile station is in packet transfer mode or MAC-Shared state. Alternatively, the mobile station may initiate random access with access type “single block without TBF establishment” (PCCCH) / “single block packet access” (CCCH) and send the PACKET CELL CHANGE FAILURE message using an allocated single uplink block.

The mobile station shall regard the network controlled cell reselection procedure as successfully completed when it has performed access and successfully completed contention resolution in the new cell.
In the following cases, the mobile station shall determine that the network controlled cell reselection procedure has failed:
- The mobile station is unable to synchronise to the new cell (see 3GPP TS 45.008) or the timer T3174 expires before a successful completion of the network controlled cell reselection procedure. Cause: 'No response on target cell'.
If the mobile station determines that the network controlled cell reselection procedure has failed, the mobile station shall stop timer T3174 (if it is still running) and start timer T3176. The mobile station shall return to the old cell, where it may trigger a cell update or other GMM specific procedure. In case the mobile station synchronised and attempted to access the new cell before returning to the old cell, the mobile station shall trigger a cell update or other GMM specific procedure, as appropriate according to the GMM requirements (see 3GPP TS 24.008).
The mobile station shall send a PACKET CELL CHANGE FAILURE message with the appropriate cause value to the network in the old cell and stop timer T3176. The PACKET CELL CHANGE FAILURE message may be sent on PACCH when the mobile station is in packet transfer mode or MAC-Shared state. Alternatively, the mobile station may initiate random access with access type 'single block without TBF establishment' (PCCCH) / 'single block packet access' (CCCH) and send the PACKET CELL CHANGE FAILURE message using an allocated single uplink block.

The cell change order procedure is started by sending a PACKET CELL CHANGE ORDER message to the mobile station on the PCCCH or PACCH. Upon receipt of the PACKET CELL CHANGE ORDER message the mobile station shall start timer T3174.
When a cell reselection is made controlled by the network, the mobile station shall act upon the IMMEDIATE_REL value which has been received in the Packet Cell Change Order: if required, the mobile station shall abort any TBF in progress by immediately ceasing to decode the downlink, ceasing to transmit on the uplink, stopping all RLC/MAC timers except for timers related to measurement reporting. The mobile station shall then switch to the identified specified new cell and shall obey the relevant RLC/MAC procedures on this new cell.

The cell change order procedure is started by sending a PACKET CELL CHANGE ORDER message to the mobile station on the PCCCH or PACCH. Upon receipt of the PACKET CELL CHANGE ORDER message the mobile station shall start timer T3174.
When a cell reselection is made controlled by the network, the mobile station shall act upon the IMMEDIATE_REL value which has been received in the Packet Cell Change Order: if required, the mobile station shall abort any TBF in progress by immediately ceasing to decode the downlink, ceasing to transmit on the uplink, stopping all RLC/MAC timers except for timers related to measurement reporting. The mobile station shall then switch to the identified specified new cell and shall obey the relevant RLC/MAC procedures on this new cell.
When cell reselection is controlled by the network, the mobile station in packet transfer mode shall act upon the IMMEDIATE_REL value: it may continue its operation in the old serving cell, as in mobile steered cell reselection, or it shall immediately abort its TBF if it is indicated by the IMMEDIATE_REL value.
Under no circumstances, operations in the old cell shall be continued more than 5 s after a cell reselection has been determined.

The cell change order procedure is started by sending a PACKET CELL CHANGE ORDER message to the mobile station on the PCCCH or PACCH. Upon receipt of the PACKET CELL CHANGE ORDER message the mobile station shall start timer T3174.
When a cell reselection is made controlled by the network, the mobile station shall act upon the IMMEDIATE_REL value which has been received in the Packet Cell Change Order: if required, the mobile station shall abort any TBF in progress by immediately ceasing to decode the downlink, ceasing to transmit on the uplink, stopping all RLC/MAC timers except for timers related to measurement reporting. The mobile station shall then switch to the identified specified new cell and shall obey the relevant RLC/MAC procedures on this new cell.
To initiate the normal routing area updating procedure, the MS sends the message ROUTING AREA UPDATE REQUEST to the network, starts timer T3330 and changes to state GMM-ROUTING-AREA-UPDATING-INITIATED. The message ROUTING AREA UPDATE REQUEST shall contain the P-TMSI signature when received within a previous ATTACH ACCEPT or ROUTING AREA UPDATE ACCEPT message.
If the routing area updating request has been accepted by the network, a ROUTING AREA UPDATE ACCEPT message shall be sent to the MS. The network may assign a new P-TMSI and/or a new P-TMSI signature for the MS. If a new P-TMSI and/or P-TMSI signature have been assigned to the MS, it/they shall be included in the ROUTING AREA UPDATE ACCEPT message together with the routing area identification.

Initial conditions
System simulator:
2 cells, GPRS supported, Carrier 1 is active, at –60dBm. Carrier 2 is on, at low level –70dBm (in order to prevent sync reading suspension due to unsuccessful synchronization attempts). PBCCH is not present on Cell A (Carrier 1), and not present on Cell B (Carrier 2). NETWORK_CONTROL_ORDER is set to NC0, and Network Mode of Operation is set to NMO 2, on both Carrier 1 and Carrier 2. Cell A in MCC1/MNC1/LAC1/RAC1, cell B in MCC1/MNC1/LAC1/RAC2.
Mobile Station:
MS is in Packet Idle mode and GPRS attached.
PDP context established.
Specific PICS Statements
-
PIXIT Statements
-
Foreseen final state of the MS
- MS is in Transfer mode on carrier 2.
Test procedure
The MS is brought into downlink packet transfer mode on carrier 1 in Cell A. The SS sends a PACKET MEASUREMENT ORDER message, setting NETWORK_CONTROL_ORDER to NC2. The SS raises carrier 2 (Cell B) with higher RF signal strength than carrier 1. The MS shall stay camping in the cell A.
During the transfer, the SS sends a PACKET CELL CHANGE ORDER message. The MS shall reselect carrier 2, MS will send a ROUTING AREA UPDATE REQUEST message and SS establishes a new downlink TBF
The SS accepts the P-TMSI and returns ROUTING AREA UPDATE ACCEPT message without any P-TMSI. Further communication MS - SS is performed by the P-TMSI.
NOTE: After ROUTING AREA UPDATE COMPLTE on carrier 2 and during the UL TBF, T3158 may expire and thus PACKET MEASUREMENT REPORT is sent there. The SS shall be prepared for this.

When a cell reselection is made controlled by the network, the mobile station shall act upon the IMMEDIATE_REL value which has been received in the Packet Cell Change Order: if required, the mobile station shall abort any TBF in progress by immediately ceasing to decode the downlink, ceasing to transmit on the uplink, stopping all RLC/MAC timers except for timers related to measurement reporting. The mobile station shall then switch to the identified specified new cell and shall obey the relevant RLC/MAC procedures on this new cell.
To initiate a combined routing area updating procedure the MS sends the message ROUTING AREA UPDATE REQUEST to the network, starts timer T3330 and changes to state GMM-ROUTING-UPDATING-INITIATED and MM LOCATION UPDATING PENDING. The value of the update type IE in the message shall indicate "combined RA/LA updating". If for the last attempt to update the registration of the location area a MM specific procedure was performed, the value of the update type IE in the ROUTING AREA UPDATE REQUEST message shall indicate "combined RA/LA updating with IMSI attach". Furthermore the MS shall include the TMSI status IE if no valid TMSI is available.

Initial conditions
System simulator:
2 cells, GPRS supported, Carrier 1 is active, at –60dBm. Carrier 2 is on, at low level –70dBm (in order to prevent sync reading suspension due to unsuccessful synchronization attempts). NETWORK_CONTROL_ORDER is set to NC0, and Network Mode of Operation is set to NMO I, on both Carrier 1 and Carrier 2. Cell A in MCC1/MNC1/LAC1/RAC1, cell B in MCC1/MNC1/LAC1/RAC2.
Mobile Station:
MS is in Packet Idle mode and GPRS attached (P-TMSI 1, P-TMSI signature 1). Ready timer deactivated.
PDP context established.
Specific PICS Statements
- MS operation mode A (TSPC_operation_mode_A)
- MS operation mode B (TSPC_operation_mode_B)
- MS operation mode C (TSPC_operation_mode_C)
PIXIT Statements
-
Foreseen final state of the MS
- MS is in Transfer mode on carrier 2.
Test procedure
The MS is brought into downlink packet transfer mode on carrier 1 in Cell A. The SS sends a PACKET MEASUREMENT ORDER message, setting NETWORK_CONTROL_ORDER to NC2. The SS raises carrier 2 (Cell B) with higher RF signal strength than carrier 1. The MS shall stay camping in the cell A.
During the transfer, the SS sends a PACKET CELL CHANGE ORDER message. The MS shall reselect carrier 2.
In Cell B, the MS sends a ROUTING AREA UPDATE REQUEST message. The SS accepts the P-TMSI signature and returns ROUTING AREA UPDATE ACCEPT message without any P-TMSI nor any new TMSI but Force to Standby set. Further communication MS-SS is performed by the old P-TMSI.
NOTE: during the UL TBF, T3158 may expire and thus PACKET MEASUREMENT REPORT is sent there. The SS shall be prepared for this.

The behaviour of the mobile station is controlled by the NETWORK_CONTROL_ORDER parameter in a PACKET MEASUREMENT ORDER message. The reporting periods are indicated in the NC_REPORTING_PERIOD_T field of the PACKET MEASUREMENT ORDER message. The mobile station shall apply to the timer T3158 the NC_REPORTING_PERIOD_T when in packet transfer mode.
The procedure for NC measurement report sending shall be initiated by the mobile station at the expiry of the NC measurement report interval timer T3158. At expiry of the timer T3158 the mobile station shall restart the timer T3158, perform the measurements and send the PACKET MEASUREMENT REPORT message containing the 'NC measurement report struct' on PACCH.
Paging initiation using PACCH applies when sending a paging request message to a mobile station that is GPRS attached, when the mobile station is in packet transfer mode and the network is able to co-ordinate the paging request with the radio resources allocated for the mobile station on a PDCH. This kind of paging co-ordination shall be provided in network mode of operation I (see 3G TS 23.060). This kind of paging co-ordination may be provided also in network mode of operation II or III. This kind of paging co-ordination shall be provided if the network supports DTM.
When the mobile station responds to a paging request for RR connection establishment, it shall follow the paging response procedures as specified in 3GPP TS 04.18. For that purpose, a mobile station in packet transfer mode or a mobile station that has initiated a packet access procedure may abort any ongoing TBF or the packet access procedure in the following two cases:
- The mobile station requires that the BSS co-ordinates the allocation of radio resources for an RR connection and a simultaneous TBF (GPRS class A mode of operation by means of DTM).

[3GPP TS 44.060, 8.1.3]
If CCN is enabled (see subclause 5.5.1.1a, 3GPP TS 44.160 subclause 5.4.1.3), the mobile station shall behave as in network control mode NC0 or NC1 up to the point when a new cell has been chosen. It shall then check the CCN_SUPPORTED parameter, if available, that was last received for that cell. This parameter can be sent on BCCH or PBCCH or individually in PACKET MEASUREMENT ORDER or PACKET CELL CHANGE ORDER messages.
If it is available and if it indicates that CCN mode shall not be entered towards that cell, then the mobile station shall perform the cell change and not enter CCN mode.
If it is available and if it indicates that CCN mode shall be entered towards that cell or if it is not available, then instead of performing the cell change, the mobile station shall start timer T3206 and enter the CCN mode. At the first possible opportunity, the MS shall then, when in CCN mode, inform the network about the proposed cell by sending a PACKET CELL CHANGE NOTIFICATION message, stop timer T3206, start timers T3208 and T3210. The PACKET CELL CHANGE NOTIFICATION message shall contain the ARFCN for the BCCH and the BSIC as identity of the proposed cell. The message shall also contain measurement reports for the proposed cell and for other neighbour cells if available. In CCN mode the mobile station shall continue the data transfer and store neighbour cell system information if received in instances of the PACKET NEIGHBOUR CELL DATA message, but not perform the cell change. At receipt of the first PACKET NEIGBOUR CELL DATA message or PACKET CELL CHANGE CONTINUE message or PACKET CELL CHANGE ORDER message, the mobile station shall stop the timer T3210.
The mobile station shall retransmit the PACKET CELL CHANGE NOTIFICATION message once at the first possible opportunity when the timer T3210 expires.
The mobile station shall leave CCN mode when either CCN is no longer enabled (towards all neighbour cells with the CCN_ACTIVE bit or towards the cell that had been re-selected) or when the network has responded with a PACKET CELL CHANGE CONTINUE or PACKET CELL CHANGE ORDER message or when either of the timers T3206 or T3208 have expired.

• RLC/MAC control blocks containing a Packet Cell Change Notification message;
• Other RLC/MAC control blocks, except Packet Uplink Dummy Control Blocks;
• RLC data blocks;
• RLC/MAC control blocks containing Packet Uplink Dummy Control Blocks.
[3GPP TS 44.060, 8.1.2.2]
Whenever the mobile station receives an RLC data block addressed to itself and with a valid RRBP field in the RLC data block header (i.e., is polled), the mobile station shall transmit a Packet Downlink ACK/NACK message in the uplink radio block specified by the RRBP field whatever the BSN value of the received RLC data block, unless another RLC/MAC control message is waiting to be transmitted, in which case the other RLC/MAC control message shall be sent. Among the other RLC/MAC control blocks the PACKET CELL CHANGE NOTIFICATION message shall be sent with highest priority. However, the mobile station shall transmit an RLC/MAC control message other than a PACKET DOWNLINK ACK/NACK message at most every second time it is polled. Furthermore the mobile station shall not transmit an RLC/MAC control message other than a PACKET DOWNLINK ACK/NACK message if the PACKET DOWNLINK ACK/NACK message would contain a Final Ack Indicator or Channel Request Description IE. The mobile station shall not send a PACKET CONTROL ACKNOWLEDGEMENT message unless otherwise specified.
[44.060, 8.8.3]
After receiving a PACKET CELL CHANGE NOTIFICATION message from the mobile station the network can behave in different ways as described below.
1) The network responds with a PACKET CELL CHANGE CONTINUE message.
If a mobile station as response to a PACKET CELL CHANGE NOTIFICATION message receives a PACKET CELL CHANGE CONTINUE message without receiving any neighbour cell system information, the mobile station shall stop timer T3208, stop timer T3210 if still running, leave CCN mode and continue cell reselection in NC0/NC1 mode.

[3GPP TS 44.060, 5.5.1.4.3]
A mobile station supporting the Network Assisted Cell Change procedures shall implement the request for acquisition of system information (see clause 5.5.1.1a).
The PACKET PSI STATUS (respectively PACKET SI STATUS) message shall indicate the present status of PSI (respectively SI) messages stored in or requested but not received by the mobile station. The mobile station shall include as many PSI (respectively SI) message types that fit into the Received PSI Message List (respectively Received SI Message List) construction in the PACKET PSI STATUS (respectively PACKET SI STATUS) message and that meet the following criteria: The PACKET PSI STATUS (respectively PACKET SI STATUS) message is sent on PACCH when the mobile station is in packet transfer mode. The first sending of this message during the acquisition of PBCCH (respectively BCCH) information shall take place at the first suitable opportunity after the acquisition is initiated:
- The PSI (respectively SI) message type is relevant for the mobile station, based on the features the mobile station supports (e.g. non-GSM and multi-RAT capabilities); and
- In case of optional PSI (respectively SI) messages types, the PSI (respectively SI) message type shall be indicated by the network as present on PBCCH (respectively BCCH).
If the presence of an optional PSI (respectively SI) message type cannot be determined, based on the information received, the mobile station shall assume that the optional PSI (respectively SI) message type is present.
NOTE 1: On PBCCH, the presence of optional PSI messages is indicated in PSI1 and PSI2.
NOTE 2: On BCCH, SI2, SI3, SI4 and, if present, SI9 indicate the presence of optional SI messages, except SI1. The presence of SI1 can be determined by reading the BCCH Norm block at TC = 0.
The message type value for these PSI (respectively SI) messages shall be included in the Received PSI Message List (respectively Received SI Message List) in the PACKET PSI STATUS (respectively PACKET SI STATUS) message. The network may use this information to determine which PSI (respectively SI) message types the mobile station is able to receive and the present status of the PSI (respectively SI) messages stored in the mobile station.
[3GPP TS 44.060, 8.8.3]
After receiving a PACKET CELL CHANGE NOTIFICATION message from the mobile station the network can behave in different ways as described below.
3) The network sends first necessary system information for the cell proposed in the PACKET CELL CHANGE NOTIFICATION message, or for any other cell, in one or more instances of the PACKET NEIGHBOUR CELL DATA message and sends then a PACKET CELL CHANGE ORDER message.
The mobile station shall store the received system information as specified in clause 8.8.1. When the first instance of the PACKET NEIGHBOUR CELL DATA message is received, the mobile station shall stop timer T3210 if still running. When the PACKET CELL CHANGE ORDER message is received, the mobile station shall stop timer T3208, leave CCN mode and follow the procedures as specified for the Packet Cell Change Order (clause 8.4) and in clause 8.8.1.

Initial conditions
System Simulator:
3 cells, GPRS supported, CCN Active in SI13, PCCCH not present.
GPRS ready timer T3314 = infinity
Cell A: The indication of Cell C is removed in SI2. RLA_C = -50 dBm
Cell B: Supports PACKET SI STATUS. No System Information is broadcast on the BCCH, except SI3. This is only made to make it possible to verify that the MS uses the information in Packet Neighbour Cell Data. RLA_C = -60 dBm
Cell C: The cell is not active at the start of the test.
Mobile Station:
MS is in Packet Idle mode, GPRS attached with support of GERAN Feature Package 1 indicated in MS Radio Access Capabilities, and PDP context 2 established.

Test procedure
The MS is triggered to initiate packet uplink transfer. SS assigns resources to the MS and it starts to send uplink data that the SS acknowledges. During the uplink the signal strength of cell A is lowered to – 80 dBm. The MS enters CCN mode and sends PACKET CELL CHANGE NOTIFICATION. The MS then continues to send uplink data. SS sends a complete set of PACKET NEIGHBOUR CELL DATA with SI1, SI3 and SI13 of Cell B to the MS. The SS then sends a PACKET CELL CHANGE ORDER that orders the MS to change to Cell B.
The MS requests resources for an uplink in the Cell B and continues the uplink. The MS then requests the remaining SI messages by sending PACKET SI STATUS(Note: During the acquisition of BCCH information the MS may send up to three extra PACKET SI STATUS messages). SS verifies that the MS indicates that it has received the SI sent in PACKET NEIGHBOUR CELL DATA. SS sends the missing SI to the MS in PACKET SERVING CELL DATA messages during the uplink.
To ensure that the MS has received the requested SI, Cell A is deactivated and Cell C is activated with signal strength set to – 50 dBm. The signal strength of cell B is lowered to – 80 dBm. The MS enters CCN mode and sends PACKET CELL CHANGE NOTIFICATION. The SS then sends PACKET CELL CHANGE ORDER and the MS changes to Cell C. The MS requests resources for an uplink in the new cell and re-establishes and completes the uplink transfer in the new cell.

The SI2quater message may also contain information, the CCN Support description, to be used when CCN is enabled in the serving cell, see 3GPP TS 44.060. This CCN Support description is associated with the Neighbour Cell list (see 3.4.1.2.1.3) having the same BA_IND value and 3G_BA_IND value. Each CCN_SUPPORTED bit of this field relates to indices of the Neighbour Cell list, starting with index 0. The CCN Support description may be received before the corresponding Neighbour Cell list.
Indices exceeding the value 95 or the number of cells in the Neighbour Cell List shall be ignored. If there are fewer indices than the number of cells in the Neighbour Cell List, the value 0 shall be assumed for the missing bits.
When this information is not present but CCN is enabled in the serving cell, the mobile station shall assume that CCN is enabled towards all neighbour cells.
